A recursive approach (which is what I would use) would involve breaking the problem into isomorphic subproblems: to find all permutations of a string, find all permutations of the string without a ...

The Permutation Generator lab currently requires people to create a recursive function to form an array of possible permutations of a string. But the way it wants that to happen seems to be very ...
